Project

MERITS is an R&D project supported by the European FP7 program with the aim to build a prototype of a compact rechargeable heat battery.

Such a product would offer a solution for improved use of renewable sources for domestic heating, cooling and hot water applications and it would thus greatly contribute to the European ambition of an energy-neutral built environment by 2050.

 

The project is carried out by four research institutes (TNO, VITO, Tecnalia, Fraunhofer), two universities (Ulster University, University of Lleida), two SMEs (De Beijer RTB, Zonne-energie Nederland BV), and two industries (Mostostal, Glen Dimplex). 


The team will work with novel high energy density thermochemical materials that can supply required heating, cooling and domestic hot water for a dwelling with up to 100% renewable energy sources (e.g. the sun) throughout the year.

The key development issues are 1) the delivery of heat on different dedicated temperature levels for heating, cooling and domestic hot water, 2) the tailoring to the requirements of individual dwellings, 3) the design and development of a dedicated solar collector, and 4) the integrated design for the different components and enhanced thermo-chemical materials, including the control system. Furthermore, the project includes the development of business models and market strategies to foster market take-up before 2020.

The project works according to the following work packages:
